DETAILED DESCRIPTION

[0028] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0029] Specific embodiment one: the embodiment is a methanol extraction column control device.

[0030] As shown in Figure 1 , Figure 2 and Figure 3 , the inside of the limiting frame 1 is provided with a slot 2, the slot 2 is slidably connected with the first moving block 3 and the second moving block 5, the first moving block 3 is rotatably connected with the connecting plate 4, the connecting plate 4 is rotatably connected with the second moving block 5, the upper side of the connecting plate 4 is provided with a connecting shaft 6, the connecting shaft 6 is rotatably connected with a connecting rod 7, the connecting rod 7 is fixedly connected with the output shaft of a motor 8, and the motor 8 is fixedly connected with the limiting frame 1 through a connecting frame.

[0031] As shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the lower side of the limiting frame 1 is provided with a hollow column 9, the hollow columns 9 are arrayed, the hollow columns 9 are threadedly connected with threaded columns 10, the lower side of the threaded columns 10 is provided with rubber pads 11, the hollow columns 9, the threaded columns 10 and the rubber pads 11 are one-to-one corresponding, the connecting plate 4 is fixedly connected with a connecting disc 12, the upper side of the connecting disc 12 is fixedly connected with a connecting column 13, the connecting column 13 is fixedly connected with an extraction column body 14, the side of the extraction column body 14 is provided with a high-low temperature thermostat 15, the high-low temperature thermostat 15 is fixedly connected with an output pipe 16, the output pipe 16 is fixedly connected with a connecting pipe 17, the connecting pipe 17 penetrates through the upper side of the extraction column body 14, the connecting pipe 17 is fixedly connected with a reflux pipe 18, and the reflux pipe 18 is fixedly connected with the extraction column body 14.

[0032] It needs to be explained that in the extraction tower body 14, the mixture containing methanol and water and the extractant are fed from the feed port at the top of the extraction tower body 14, and the raw material mixture in the extraction tower body 14 will be in contact with the extractant, so as to realize the separation of methanol and water. When the extraction is finished, open the valve at the lower side of the extraction tower body 14, and the separated methanol and water can be discharged from the extraction tower body 14. The extraction is affected by temperature, and the high-low temperature thermostat 15 can produce constant temperature liquid. High temperature is conducive to the reaction of the extractant and methanol in the extraction tower body 14, and reduces the extraction time. These liquids are transported into the connecting pipe 17 through the output pipe 16. Since the connecting pipe 17 penetrates through the limiting frame 1, the connecting pipe 17 will be in contact with the extractant and the mixture, which facilitates the extraction. The liquid in the connecting pipe 17 finally flows back to the high-low temperature thermostat 15 through the reflux pipe 18, reducing the waste of energy.

[0033] Specific embodiment two: this embodiment is to solve the problem of long extraction time of the extraction tower body 14 when it is at rest.

The motor 8 is connected with the limiting frame 1 through the connecting frame, and the width of the connecting frame is large, so that the extraction tower body 14 will not be in contact with the connecting frame during movement. Start the motor 8. When the motor 8 is working, it will make the connecting shaft 6 do circular motion through the connecting rod 7, and the connecting shaft 6 is arranged on the upper side of the connecting plate 4, so that the connecting plate 4 will move when the connecting shaft 6 moves, and the connecting rod 7 on the lower side of the connecting shaft 6 is affected by the first moving block 3 and the second moving block 5. When the connecting plate 4 is rotated by the connecting rod 7, the first moving block 3 and the second moving block 5 also limit the connecting plate 4 at this time, so that the connecting plate 4 does elliptical motion, and then controls the connecting disc 12 and the connecting column 13 to make the extraction tower body 14 do elliptical motion, which facilitates the extraction of the extraction tower body 14.

[0035] Specific embodiment three: this embodiment is to solve the problem that if the limiting frame 1 is inclined when it is placed, it is not conducive to the elliptical motion of the extraction tower body 14.

[0036] As shown in Figure 1 , Figure 2 and Figure 3As shown, if the limiting frame 1 is directly placed on the workbench, due to the large contact area, the limiting frame 1 is prone to shaking when the extraction tower body 14 performs an elliptical motion, since the hollow column 9 at the lower side of the limiting frame 1 is threadedly connected with the threaded column 10, the threaded column 10 is rotated to allow the threaded column 10 to move downward with the rubber pad 11 and tightly adhere to the workbench, all the threaded columns 10 are adjusted, and the extraction tower body 14 is in a horizontal state, thereby facilitating the control of the extraction tower body 14 to perform extraction.
